FLUID AND GAS TRAP.

"` I i Application nled January 23, 1828. Serial No. 248,857.

By way of illustration it might .be stated that in oil wells wherein a acker isused to exclude water from the ottoni of the well, the gas collects between the bottom of l the well and packer to shut off the ow of oil to the well, thereby cutting down production and eventualll spoiling the well.

It is therefore t e object of the present invention to provide a gas relief device 10 which may be operated to release gas at the ,bottom of the well to reduce pressure and.

insure a capacity fiow of oil. v Another object of the invention is to provide means on the pump rod for contacting u lo with the relief device to operate the" relief device for releasin the gas. c With the foregoing-and-other ObJects. in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in. the details of construction hereinafter described and claimed,I it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without ,e de artin from the spirit ofthe invention.

eferring to the drawing: Figure 1 is a longitudinal sectional view through a well casing, thewell tubing with which the device is used, being shown in elevation. A

Figure 2 is a longitudinal sectional view through the gas trap.

Figure 3 is a fragmental sectional view illustrating a modified` form of valve.

Referrin reference c aracter 5 designates a well casing which is of the usual and well known well tubing. 4

Thel relief valve forming the essence of the invention is used in connection with oil or vgas wells wherein a packer isemployed for vpreventing the flow 'of water into the bottom of the well,` the ,packer being indicated by the. reference character 7 and surroundsthe well tubing 6 and closely engages the well casing 5. d

The.v reference character 8 indicates a tremities to be connected with the well tubwhich the valve 11 seats, and normally rests,

the valve 11 being tapered to closely t the seat. v

lupwardly a predetermined to the drawing in detail, the.

construction, and in which is positionedthe length of tubing formed with threaded exv At the upper end of the valve- 11 is a reduced portion 12 threaded to receive the alower internal threads of the tubular body portion 13 of the trap. At the upper end of the body portion 13 is a head 14 formed with a flange that cooperates with the upper end of the tubular body. portion to clamp upwardly through' the trap during the pumping `operation, and at the same time provide passageways to permit a portion of the gas to pass through the tra when the 4valve is elevated. Formed in t e section 8 are bores 18 throuh which the gas may enter the interior o the tube 6 from where it passes upwardly and exhausts at the top ofthe tubing. z

' As clearly shown b Figure 2 of the drawing, the pump rod w ich is indicated bythe re erence character 19 passes throu h the valve 11 and head 14, the head an valve being provided with bores greater in diameter than the pump rod providing passageways through which wardly through the va ve.

Formed on the pum rod at a point in spaced relation with t e valve 11 are laterally extended lugs'20, while at a. oint above the head 14 4are laterally extendedp lugs 21, the lugs 20 beingdesigned to contact with the valve 11 when the pum rod is moved istance, to lift the valve 11 from its seat uncovering bores 18, so that gas may pass upwardly around as may pass upthe valve and through Openings 17 entering the interior of the valve.

ln the form of the invention as shown h Fi re 3 the removable tubular section is' 'i in icated by the reference character 8f`and;.,f

endsA extendedthrough the valve seat indicated at 10. The --valve in this form and which is indicated by the reference character 11 is formed with a plurality of vertical bores 17 through which oilpasses while the valve oli its seat so that gas may passl through bores 18 and upwardly around the valve 11 to exhaust through the top of the tubing in which the trap is positioned. It

is formed withbores 18 having their inne no I limits oi? its normal puming stroke to accomplish the operation of t e relief va ve, is imparted to the pump rod through the aiusting screw. s 22, which has" connection with the upper end of the pump rod; and with the beam 237 to the enel that slight 'movement' ef the adjusting screw 'will tend to seat or unseat the valve to release the gas or return the valve to its seat.

I claim: f l. In combina-tion with the `Well tubing and sucker rod. of an oil Well, a tubing section having an inclined valve seat formed ina--- teriorly tliereo and having a plurality of epenings extending to the valve seat, a 13eliet valve ineludin a vertically movable l elongated member, t e lovver end of the reliet valve having bores normally registermg with the interior of the tubing it which the valve is positioned, means on the sucker rod for engaging the valve to move the valve `from its seat, and means on the sucker rod for returnin the valve to its seat.

2. In com ination vvith the Well tubing l and sucker rod of an oil Well, a tube section having bores extending therethrough 'and having a valve seat formed interiorly there of, a vertically movable valve having bores at its lower end and bores at its upper end, said valve adapted tol normally close .the bores of the tubesection, means on the sucker rod for Vengaging the lower end of the valve to elevate the valve and permit gas to pass through the bores thereof, and means on the sucker rod. and engaging the u per end of the valve for moving the valve E on its seat.

ownvvardly In testimony that I claim the foregoing my ovvn, I have hereto aixed my signature. v
